Embodiment Construction
[0027] Such as Figure 1-15 As shown, an electric combined vibration type grain grading device is composed of a rear-end frequency conversion motor 1, a rear-end motor seat 2, a transmission shaft 3, a spring sliding support 4, a universal roller 5, a left connecting rod 6, a rear crank 7, Slider 8, connecting rod 9, lower connecting piece 10, base 11, right connecting rod 12, front-end variable frequency motor 13, front-end motor seat 14, front crank 15, front connecting rod 16, front connecting piece 17, grain bin 18, etc. composition. Wherein rear crank 7, slide block 8, connecting frame rod 9, lower end connector 10 etc. form a swing guide rod mechanism. This mechanism swings back and forth around the hinge point between the connecting frame rod 9 and the lower end connecting piece 10 through the drive shaft 3 and driven by the rear-end variable frequency motor 1; at the same time, through the left connecting rod 6 and right connecting rod 12, the grain bin 18 around the...

Abstract
An electric combined vibration type grain grading device, which consists of a rear-end frequency conversion motor, a rear-end motor seat, a transmission shaft, a spring sliding support, a universal roller, a left connecting rod, a rear crank, a slider, a connecting rod, and a lower connecting piece , base, right connecting rod, front-end variable frequency motor, front-end motor seat, front crank, front connecting rod, front connecting piece, grain bin, etc. Wherein the rear crank, slide block, connecting frame rod, lower end connector etc. form a swing guide rod mechanism. This mechanism swings reciprocatingly around the hinge point between the connecting frame rod and the lower end connecting piece through the drive shaft and driven by the frequency conversion motor at the rear end; at the same time, through the left connecting rod and the right connecting rod, the grain bin rotates around the hollow cylinder on the upper part of the base. The center of the bottom surface of the shaped slideway performs reciprocating left and right shimmy. The invention has the characteristics of high delamination efficiency, large delamination energy, stable operation and long service life.
Description
technical field [0001] The invention relates to an electric combined vibration type grain grading device, which belongs to a separation device for removing impurities from grain. It can also be used for the separation and classification of Chinese herbal medicine seeds, grass seeds and impurities. Background technique [0002] In ancient China, the working people have used the principle of segregation and separation of particles to sieve grains when different particles are subjected to vibration and impact. "Shiyu Xinshuo" "Win the wind and raise it, and the chaff comes first." This sentence is a good proof of this point. However, traditional devices rely entirely on manpower, have poor grading efficiency and high labor intensity, and cannot adapt to the current trend of agricultural mechanization. [0003] The invention adopts a frequency conversion motor as a power source and uses combined vibration to simulate the process of people using sieves to sieve grains in real l...
